山地城市复杂路口交通组织优化研究

Traffic organization optimization at complex intersection of mountain cities

复杂路口是城市交通的瓶颈,合理的交通组织是提高复杂路口通行能力的重要途径。从分析几何特征、交通运行及管理特征出发,提出复杂路口交通组织优化流程和方法。以重庆市某复杂路口为例进行交通组织优化研究,利用SIDRAINTERSECTION交通仿真软件对交通组织优化方案进行仿真分析,结果表明,对复杂路口进行交通渠化、信号配时结合的交通组织优化可以明显改善交通运行状况,提高交叉口的运行效率。

Complex intersection is the bottle-neck of urban traffic. Reasonable traffic organization is an important way to improve the capacity of complex intersection. Based on the geometric features, traffic operation and management, a method of traffic organization optimization at complex intersection is proposed. A case study in Chongqing is shown, in which the software, SIDRAINTERSECTION, is used to analyze the traffic organization optimization schemes. The results show that this method can combine traffic channelization with traffic signal control to significantly improve the traffic movements and increase the efficiency.
